How do people conceptualise the reuse of medicines? An interview study

Objectives To capture people's beliefs about medicines reuse and to map the determinants of intentions to reuse medicines in the future. Methods Participants were recruited through an advert placed in the university's community newsletter reaching 15 000 households. Adults wishing to participate were interviewed using convenience sampling, with recruitment continuing until data saturation. Participants were interviewed face‐to‐face by two researchers using a semi‐structured interview schedule based on the theory of planned behaviour ( TPB ). Interview transcripts were analysed by thematic analysis, with the themes classified according to the TPB . The University's research ethics committee approval was obtained. Key findings Nineteen participants were interviewed. The potential economic and environmental benefits of medicines reuse were juxtaposed with stability and safety worries. Participants trusted pharmacists to quality‐assure returned medicines, but wondered if they had the time and storage space to dedicate to medicines reuse. Environmentalists were seen as the main proponents of medicines reuse with drug manufacturers, some taxpayers and parents seen as the main opponents. The physical characteristics of reused medicines, and quality assurance and logistics of reuse processes were seen to enable/obstruct engagement in medicines reuse. A working definition of medicines reuse as a behaviour was developed. Conclusions People could potentially agree to reuse medicines if their concerns are addressed and the process is well defined and managed. This is a qualitative study with a small number of participants meaning the results may not be generalisable. The themes generated will enable a structured questionnaire to be developed for quantifying broader views.
